This invention relates to sprinkler heads, and in particular to devices, guards and shields and methods for both protecting sprinkler heads and also deter grass and weeds from growing adjacent to the sprinkler heads, which can be applied to most if not all sprinkler heads available on the market, and also use a safe replaceable herbicide.

Inground sprinkler heads are prone to becoming damaged from lawn mowers, walking traffic and vehicles. The undesirable impacts on the plastic head parts will often result in broken sprinkler heads that require repairs and often must be replaced. Such repairs and replacement of the sprinkler heads can be quite expensive on residential lawns that that have dozens of installed sprinkler heads. The problem is further compounded in commercial lawns and golf courses.

Another problem with sprinkler heads is that it can be expensive and time consuming to constantly trim unwanted vegetation such as grass and weeds from growing up around the sprinkler heads. The undesirable vegetation can result in obstructing the side spray from being emitted from the heads which limits the amount of ground cover to be sprayed from the sprinkler heads.

Often lawn maintenance workers will use mowers to try to cut the unwanted vegetation around the heads. However, the mowers can damage and destroy the sprinkler heads if they get too close. More often than not the mowers will not effectively cut the unwanted vegetation immediately around the sprinkler heads. Other types of popular tools have included edge trimmers and gas or electric power line trimmers. However, these tools can also easily damage or destroy the plastic parts on sprinkler heads. Another alternative is to have the lawn maintenance worker to physically pull the unwanted vegetation by hand. However, this technique can become quite expensive and time consuming per job.

Over the years various types of sprinkler head shields and guards have been proposed. See for example, U.S. Pat. No. 5,772,118 to Fabiano describes a sprinkler head shield that requires the shield to be screwed to the base of the sprinkler head, which would be time consuming to attach as well as not be able to be used with all the different types of the sprinkler heads on the market. Also, this shield does not deter or prevent unwanted vegetation from growing up adjacent to the sprinkler heads.

U.S. Pat. No. 2,080,341 to Schumacher; Des. 256,386 to Bergland; U.S. Pat. No. 7,216,819 to Bernards and U.S. Pat. No. 7,946,507 to Gauthier, III each show shields having generally disc shaped configurations with central holes for fitting about a sprinkler head. However, these shields do not deter or prevent unwanted vegetation from growing up adjacent to the sprinkler heads.

U.S. Pat. No. 3,015,448 to Hurless and the product SPRINKLER SAVER® each show devices having portions that must be inserted into the ground or snap about the neck portions around the sprinkler heads. However, these types of guards can require extra labor to have portions inserted into the ground, and cannot universally work with all the different types of sprinkler heads on the marks. Also, these guards do not deter or prevent unwanted vegetation from growing up adjacent to the sprinkler heads.

Other types of prior art guards and shields use donuts that can be made of plastic and/or concrete. However, these guards and shields cannot universally work with all the different types of sprinkler heads on the market. Also, these guards do not deter or prevent unwanted vegetation from growing up adjacent to the sprinkler heads.

Thus, the need exists for solutions to the above problems with the prior art.

A primary objective of the present invention is to provide devices, guards and shields and methods for both protecting sprinkler heads and deter unwanted vegetation from growing adjacent to the sprinkler heads, which can be applied to most if not all sprinkler heads available on the market.

A secondary objective of the present invention is to provide devices, guards and shields and methods for both protecting sprinkler heads and deter unwanted vegetation from growing adjacent to the sprinkler heads, having a replaceable safe herbicide.

A third objective of the present invention is to provide devices, guards and shields and methods for both protecting sprinkler heads and also deter unwanted vegetation from growing adjacent to the sprinkler heads, which can be applied to most if not all sprinkler heads available on the market.

A sprinkler head protector and grass killer device, can include a hollow ring shaped housing having an upper side and a lower side, with a large center hole therethrough, a herbicide for being placed inside of the housing, and drainage holes passing through the upper side and the lower side of the ring shaped housing, wherein the ring shaped housing can be placed about a sprinkler head, so that water passing through the drainage holes causes the herbicide inside of the ring shaped housing to leach onto ground surfaces adjacent to the sprinkler head to prevent unwanted grass from growing adjacent to the sprinkler head while the ring shaped housing protects sides of the sprinkler head.

The upper side can include a perimeter edge having an annular groove and the lower side includes a raised edge for fitting within the annular groove of the upper side.

The upper side can include a pair of concentric annular grooves, and the lower side includes a pair of raised annular edges for fitting within the annular grooves of the upper side.

The annular groove can have an outwardly protruding ledge, and the raised edge includes an outwardly protruding ledge, so that the outwardly protruding ledge on the upper side and the outwardly protruding ledge on the lower side abut against one another when the upper side and the lower side are attached to one another.

Both of the annular grooves can have an outwardly protruding ledge, and both of the raised edges have outwardly protruding ledges, so that the outwardly protruding ledges on the upper side and the outwardly protruding ledges on the lower side abut against each other when the upper side and the lower side are attached to one another.

The upper side and the lower side can snappably attach to one another to form the ring shape.

The upper side and the lower side can be sized to tightly attach to one another to form the ring shape.

The upper side and the lower side can be formed from molded plastic.

The herbicide can be a liquid form selected from at least one of: rock salt, cornmeal, and black walnut shells.

The herbicide can be a dry herbicide selected from at least one of chlorine and vinegar.

A annular spacer 130 can be located between annular rings 110 and 120, and drainage holes 135 in the annular spacer 135. The upper section can also include a central opening 150.

Referring to FIGS. 1, 2 and 4, the lower section 200 can include a first upwardly extending inner annular ring 210 with an inner wall and an outer wall, and a capped top 212. A second upwardly extending outer annular ring 220 with an inner wall and an outer wall can be located outside the first annular ring 210, and have a capped top 221. An outwardly protruding ledge 222 can extend outwardly from second annular ring 220. A Annular channel 230 can be formed between first annular ring 210 and second annular ring 220. A first annular groove 260 can be located in the floor of the annular channel 230, with drainage holes 265 in the first groove 260. A second annular groove 270 can be located in the floor of annular channel 230 with drainage holes 275 in the second groove 270. A raised annular floor 280 can be located between the first groove 260 and the second groove 270. A central opening 250 can be down the middle of the lower section 200.

FIG. 5 is an upper perspective view of the upper section 100 and the lower section 200 of the above figures assembled into a hollow ring shaped protector 1. FIG. 6 is a lower perspective view of the assembled hollow ring shaped protector 1 of FIG. 5. FIG. 7 is another upper perspective view of the assembled hollow ring shaped protector 1 of FIG. 5. FIG. 7A is a partial cross-sectional view of the assembled hollow ring shaped protector 1 of FIG. 7. FIG. 8 is another lower perspective view of the assembled hollow ring shaped protector 1 of FIG. 5.

Referring to FIGS. 1-8, the user can place a herbicide 500 (shown in FIG. 7A) on the raised annular floor 280 in the annular channel 230 of the lower section 200. The herbicide 500 can include but is not limited to dry materials such as but not limited to rock salt, cornmeal, and black walnut shells, and the like. Alternatively, the floor portion 280 can have an indentation for holding liquid herbicides, such as but not limited to chlorine, and vinegar, and the like.

Referring to FIGS. 1-8, the upper section 100 and the lower section 200 are assembled together into a single protector 1, by pushing together the upper section 100 over the lower section 200. The bottom facing annular grooves of the first and second annular rings 110, 120 are positioned over the capped tops 212, 221 of the first upwardly extending annular ring 210 and the second upwardly extending annular ring 220 of the lower section 200. The tight fit between the upper section 100 and the lower section allows for the portions of the upper section 100 and the lower section to be sandwiched together and abutting one another as shown by outwardly protruding ledge 122 or upper section 100 contacting against outwardly protruding ledge 222 of the lower section 200. The upper section 100 and lower section are sized so that the sections 100, 200 tightly fit with each other when pushed together.

FIG. 9 shows the assembled hollow ring shaped protector 1 of FIGS. 5-8 for protecting a sprinkler head 400 and deterring unwanted vegetation 310 growing adjacent the sprinkler head.

Referring to FIGS. 1-9, the assembled protector 1 with herbicide 500 is placed over the sprinkler head 400 of an underground sprinkler. The novel protector 1 only has to be placed on the ground surface 300 and is not required to be dug into the ground surface 300.

Water from the sprinkler head 400 and/or rainwater can pass through the drainage holes 135 in the upper section 100 and into the annular channel 230 in the lower section 200 to cause portions of the herbicide 500 to drain out of drainage holes 265, 275 in the lower section onto the ground 300. The water coming from running off the herbicide 500 then kills unwanted vegetation, such as but not limited to grass, weeds, trees, roots, shrubs and any other growths from naturally growing up and obstructing sprinkler head 400.

Other types of attachments can be used besides raised ridges snapping into annular grooves. For example, snapable edges can snap into each other.

Embodiments can have donut shapes with an outer diameter of approximately five inches and an inner diameter of the central opening of approximately 2 inches. Larger sizes can include outer diameters of approximately 8.9 inches and central opening diameters of approximately 3.250 inches. The height can be approximately 1 to approximately inches. The term approximately can include +/−10%. Other sizes and dimensions can be used as needed.

While the preferred embodiment shows a generally ring shaped housing, the housing can have other geometrical shapes, such as but not limited to rectangular, square, triangular, hexagon, and other shapes and the like.

Although the upper section is shown having a generally plate shape and the lower section has a large annular channel for receiving the herbicide, the upper section and the lower section can be reversed.

While herbicides have been described, the invention can be used with other insertable materials, such as but not limited to insecticides, and the like, for killing undesirable insects, such as red ants, cockroaches, spiders, mosquitoes, and the like.

While the invention has been described, disclosed, illustrated and shown in various terms of certain embodiments or modifications which it has presumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
